To @ZZ whontz't may concern.- i

Beit known that I, LAFAYETTE v]?AL1\/iER,a

l Y citizen of theUnited States, residing at Harj risburg, lin the county of Dauphin and State of Pennsylvania, have invented new and useful Improvements in Railway-Switches, of which the following is aspeciication.

My invention has relation toimprovements v in railway-switches; and the object is to simplify-v and improve the existing art. The

' switch-points are of particular construction and detachably connected to the switch-rails, the switch-points ybeing preferably made of a Y harder material than the switch-rails to which l they areconnected.v

The invention `consists` inthev novel construction,vaggroupment, and combination of parts, as will be hereinafter fully specified and particularly pointed-'out and distinctly claimed. l

I have fullyand clearly illustrated my invention in the Iaccompanying drawings,

wherein'- Y Figure 1 is a plan view of a section of a railway-track, showing `myinvention as applied thereto. Fig. 2 is a side elevation of one of the switch rails and point.` Fig. 3 is a detail view of the front portion of one ofthe switchrails with the point detached. Fig. 4. is a sid'e elevationof oneof the switch-points. Fig. 5 is a top plan view of the front portion of one of the switch-rails.A Fig. 6 is a top plan view rails of diverging railing tracks. C desigf` nates a rail parallel to B, and D designates a rail laid parallel to A, the railsA and D conf. A stituting one track and B and C constituting the rails of the other track.

On the selected cross-tie', as at 1, are se cured plates 2, formed orprovided with ver? tical studs 2a, constitutingpivots, over which ears 3, formed with perforations, engage.I These ears 3 are securedto the switch-rails by any proper fastening means, as bolts 4, projecting thro'ingh vertical flanges 5 andthe 1 webs of the switch-rails, as indicated in Figs.

, I l and 2 of the Adrawings. The ends ofthe v switch-rails arefso pivoted vthat they aline with the respective innerrails-of the tracks that they make connection with.

` 6 and 7 designatezswitch-rails of such length vas may be desired to make the properconnection with the tracks or rails to which'they relate. The lower side of theswitch-rails base is upwardlyv inclined,las at 6, to` conform to theinclined upperl surface of the base of the mainrails, as is clearly shown in Figs. 7 and y 8. The switchandrails are made up of two parts or sections, the rails of which are con-y nected by a tie-rod 8, and the points being lconnectedbya tie-rod 9,'as shown in the draw= ings in Fig. `l. VThese tie-rods 8 and 9-corn prise platesl u., secured to the web or wall of the switch-point and-held firmly by means of boltsb, passing through the parts, as indicated in Fig. 7. From the bottom of the plates d project` horizontal arms; c, terminatingin sleeves d. These sleeves are connected by the tie-rods, having their ends inserted in the said sleeves, and bolts e, projected through the sleeves and end of the rod, as indicated in Fig. 7 of the drawings.

'A In Fig. 8 of the drawings is shown a 'modi` fied construction wherein a detachable sh.-

their front ends have` the ltreads of the rails cutaway or removed on a line parallel with the top of the webs, ras show'ng'in Fig. 3, and the points lO of the switch are slotted, as at l1, to slid-e over thel web of the switch-rails, so that the end of the points will abut against v the end of the tread ofthe switch-rails, as indieated in Fig. l of the drawings. The outer edge of the tread of 'the points 10 are cut out,

securely locked together.l "The lower side of f 'the base of the point is upwardly inclined at l0b to correspond to` the inclined upper sur-v face of the switch-rail base. The outer ends ofthe switch-rails are supported on bearingplates 2". on thejtie-plates 2c, secured to the cross-ties l.

ICO`

'It will now be perceived from the foregoing description that when the switch-points are arranged and disposed in connection with the switch-rails they can be secured together by means of the bolts h, projected through iianges setting against the Webs or Walls of the points and switch-rails, as shown in Figs. l and 2 of the drawings. It will also be perceived that the relative position of the switch rails and points are such that when they are moved to the position shown in Fig. l a train moving in the direction of the arrow will be carried over the track C B and that if the switch is carried or moved to Opposite direction a train coming from the direction indicated by the arrow will be carried over the track A D.

It has not been deemed essential to illustrate means for throwing the switch, since any of the usual appliances or mechanisms for accomplishing the purpose may be connected and utilized.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with cross-ties and main rails; of the switch-sections having their bases supported on the cross-ties and provided with upwardly-inclined lower sides conforming to the bases ofthe main rail, and formed with extensions beyond the treads thereof, the points having upwardly-inclined lower sides conforming to the bases of the switch-sections andsupported thereon, and slots receiving the extensions of the webs of the switch-sections and providing extensions located beneath the tread of the switch-sections, the horizontal arms having vertical plates, bolts securing the extensions and the vertical plates together and tie-rods connecting the horizontal arm.

'In testimony whereof I affix my signature in presence of two witnesses.
